Specification of Letters Patent.

To all whom. itmayconcern Be it known that I, HOWARD EDGAR PRos- SER, a citizen of the United States, residing at Seymour, county of Outagamie, and State of Wisconsin, have invented new and useful Improvements in Filing Systems, of

which the following is a specification.

My invention relates to improvements in filing systems.

The objectof my invention is to facilitate locating filing matter in an index, file by providing removable sub-index sheets and: by eliminating all superfluous sub-index? sheets from the file when not in use.

Heretofore it has been the practice where sub-index sheets are used, to employ them permanently in the file, thus greatly com.-

plicating the file by providing a large number of unused sheets containing sub-heads, which have no reference to any matter on file, but are merely kept therein in the expectation that an occasion for use may arise. My invention, however, provides means wherebytlie sub-head sheets may be separately stored, employed when occasion for use requires, and returned to the storage rece-ptacle in a position where they can be quickly located and again used as desired. To this end, each sub-head sheet is not only provided with the appropriate index character, but is also provided with an index character which remains out of sight when the sheet is in use, but which when the sheet is removed, indicates its proper place either in the file or in the storage receptacle er drawer.

In the drawings-Figure 1 is a perspective view of a filing caseembodying my invention, showing both the main tile and the storage file drawersin openposition, the sub-head sheets being omitted except in the first two divisions of the storage file. Fig. 2 is a detail view of one ofthe sub-sheets as it appears when removed from thefile. Fig. 3is a detailview of a few of the principal sub-divisions of the main file removed from erence characters throughout the several views.

Inthe r drawing -a filing'case 1 is pro- .videdr-with a setof files represented by drawers 2 and 3. The file 2 is the main file which normally is composed of a series fof permanent main divisionsheets 4 of ordinary type, one main sheet being employed for each letter of the alphabet, together with additlonal dlvision sheets for names I which have prefixes, such as M0 or La Patented July 23, 1912.

Index tabs 5 0n the sheets 4 are arranged uniformly at one upper corner of the sheet, I preferably the left hand corner, and are letteredsuccess'ively in alphabetical'order.

' Referring now to the auxiliary file 3, it

will be observed that this file is provided with main divisionsheet-s 7, which are identical in form with the division sheets 4 of the main file. ever, removable sub-head sheets 8 are located, one for each letter of the alphabet and each provided with a tab 9, projectingupwardlyzand bearing such letter. -The tabs 9 pertaining to the different letters are each differently located at the upper margins of theseveral sheets of each series, so that-all I of these tabs are exposed to view in the file, whereby the sub-head sheet-.may be readily seen and removed. Below the index letter on the sub-head sheet, I designate such sheet by the main index letter which designates the division of the auxiliary file and of the main file to which this sub-head sheet belongs. For-example, each of the sub-head sheets back, (or in front), of the main division sheet 7 will also bear the letter A at the same place on the front side of the sub sheet below that portion or tab 9 which is exposed when the sheet isin position in the file. The letter A designates said sheet' as pertaining to the A division of the file. Each sub-sheet in this division will therefore bear the letter A and will also hear one letter of the alphabet on the tab 9, which will be different from any other letter in said division, and the tab 9 will be difierently located at the top edge of the subsheet.

In division B the sheets 8 will all be of the same character and arrangement as in division A and will be exactly like those in division A with the exception that the lower or normally concealed letter on each of these sub-sheets will be the letter B instead of the letter A. which appears on the sheets in division A. Each of the main' divisions will thus contain a complete Between these sheets, how- I I I represent the desired sub-division and also bearing a normally concealed letterto indicate the division.

Inuse, the. main file 2 will at first contain only the main index sheets. 4. Assuming that it is desired-to place a document in said, file, a sub-sheet is' selected from the receptacle or drawer 3, the, concealed letter of which represents the' initial letter of the. name of the person whose document isto be filed, and with the .exposed'letter on tab 9 corresponding with the second letter of such persons name. For example, assuming that a document is tobe filed signed by a person whose surname is "Anderson, a sub-sheet will be selected from division A of the file 3, which has the letter no on the tab 9 and which. will, of course, bear the letter A on the concealed portion of the sheet.

This sub-sheetis placed" in main division A of the main file 2 and the documentto be filed is placedrin front of it (or to the file from persons having surnames which include the same first two letters- For example, it Mr. Aridersons document is removed, sub-sheet 9 bearing the letter n in division A will be removed 'from the main file and placed in the auxiliary file 3,

unless other'documents are in themain file from persons whose names begin with'the letters An. In this manner, the main file is kept clear of all superfluous sub-sheets, and suchsub-sheets as are therein will indicate exactly the contents of the file.

I claim- '1. A filing system comprising a main an an auxiliary file, and plural series of sub-' head sheets transposable from one file to the other, each of said files being provided with permanent main CllVlSlOIl members and each cessive letters" of the alphabet. f

2. A filing system comprising a main and when the dicate its proper division; the sub-head sheets of each series having upwardly projecting index tabs, each diflerently located .alongthe upper margin ofthe sheet from those of the-other sheets of the series, said tabs being respectively provided with sucan auxiliary "file, and plural series of sub head sheets transposable from one file to the other, each of said files being provided with permanent main division members; the subhead sheets of each series havm upwardly projecting index tabs, each di erently 10-- cated' along the upper margin of the sheet from those of the othersheet-s of the series; I

the successive tabs being respectively pro- '65. vided with successive letters of the alphabet,

and each sub-head sheet in a series being provided with a main division mark in a position .to be concealed by the other sheets L the file. 3. A filing system comprising a main and an auxiliary file, and plural series of subhead sheets transposable from onefile to the other, each of said files being rovided with permanent main division rnem ers and each of said'sub-head sheets belng marked to indicate .its proper division, the sub-head sheets of each series having upwardly projecti'ng index tabs, each differently located along the fupper margin ofthe sheet from those of the other sheets of the series; said tabs being respectively provided with successive letters of the-alphabet, the main division members being-also each tabbed and lettered at one upper corner, with successive sheets lettered alphabetically on such tabs.

- In testimony whereof I aflix my signature in the presence of two witnesses.
